To all whom it may concern:

Be it known that 1, GEORGE HIGeINsoN, mechanical engineer, of l and 2 Ham Yard, Piccadilly, London, England, have invented certain new and useful Improvements in and Relating to Temporary Binders, Loose-Leaf Ledgers, and the Like, of which the following is a specification.

This invention relates to temporary binders, loose-leaf ledgers, and the like, and has for its object to provide an improved means for temporarily binding leaves of ledgers and other documents.

A temporary binder,lo0seleaf ledger,or the like made in accordance with my invention is provided with apair of plates having filing or telescopic members passing therethrough and adapted to pass through perforations in the documents to be filed and to be drawn together by screws passing through one or more of the members on one of the plates and engaging with a nut or nuts in the corresponding member or members on the other plate, said screws being provided with worm-wheel heads and operated simultaneously by worms on a spindle.

Referring to the drawings, Figure 1 is a perspective view of oneform of temporary binder made in accordance with my invention. Fig. 2 is a cross-section on line ab, Fig. 1. Fig. 3 isa front elevation, partly in section. Fig. Ais a plan, partly in section, on line 0 d of Fig. 3. Fig. 5 is a front view of a modified form of construction.

In one form of binder made in accordance with my invention and shown in the drawings each of the plates at and bis provided with back and side flanges, one plate a being slightly smaller than the other, 6, so that the side flanges c and cl and back flange ethereof may slide within the side flanges f and g and back flange it of the other plate 7). Passing through the plate a are disposed three tubes and filing members j j jand through the plate 6 tubes 76 it 70. Within each of the tubes in 76 In of the plate 6 is disposed a screw an, adapted to engage with a nut n in the corresponding tube 1' of the other plate a, and said screws are provided with worm-wheel heads 0 and adapted to be operated by a spindle 19, carrying worms q, engaging therewith. The tubes jjz'. 0., those containing the nu ts nare of smaller diameter than the tubes k and are adapted to slide therein. At the back of each plate a and Z) is a casing r7 In one casingrare disposed blocks .9, adapted to form bearings t for the worm-spindle p and also to serve as distancepieces between the casing r and the plates (6 and Z). The blocks are provided with apertures '0 for the reception of the tubes 79 and worm-wheel heads 0. The ends of these tubes are preferably enlarged or swelled, as at w, at that portion which is within the blocks, so as to form suitable bearings for the worm-wheel heads 0, and this also prevents the tubes from being drawn through the apertures n in plates a and bin the blocks. Part of the swelled end of each tube is cut away, as at :0, so as to permit of the worm q engaging with the worm-wheel 0, and a projection 3/ is provided on each tube and adapted to engage with a corresponding slot or groove .2 in each block, as in Fig. A, to prevent the tube from being rotated. The casing is secured to the plate I), and the blocks are held in the casing by screws 2 2 passing therethrough. One end of the worm-spindle is or may be square or other section, as at 3, and adapted to be turned by a key passing through a hole A in the casing b. The tubes passing through the plate a, are provided with swelled ends and are held in blocks similar to the blocks 8, except that no provision is made for the worm-gearing.

When the parts are assembled, the two plates at and Z) are opposed to one another, so that the smaller tubes j flt into the larger tubes and the screws m 122 meet the nuts an. On turning the worm-spindlep the screws m are caused to rotate and engaging with the nuts 41 draw the plates wand?) together. Documents or pages to be filed having been punched and previously placed on the tubes are firmly held by the plates when drawn together.

Fig. 5 shows a modified form wherein four sliding tubular members are employed. In this case two only of said sliding members .would be operated by worm-gear, preferably A temporary binder, loose-leaf ledger, or

the like made in accordance with my invention is neat in appearance, as none of the working parts are exposed or visible. The method of securing the tubes in position permits of a little lateral play, and the screws and wormwheel heads are perfectly free from the casing and plate. The parts being interchangeable, the apparatus is very cheap in manufacture.

What I claim, and desire to secure by Letters Patent, is-

1. In a temporary binder, two plates, two non-rotative tubular binding members adapted to telescope one within the other, and a screw arranged to rotate in one of said members and to engage the other of said members, said firstnamed member having an enlarged tubular head and said screw having a worm-wheel at its end fitting within said head, whereby the latter forms a bearing for said worm-wheel.

2. In a temporary binder, two plates, two non-rotative tubular binding members adapted to telescope one within the other, a screw arranged to rotate in one of said members and to engage the other of said members, said firstnamed member having an enlarged tubular head and said screw having a worm-wheel at its end fitting withinsaid head, whereby the latter forms a bearing for said worm-wheel, a worm engaging said worm-wheel and adapted to rotate said screw, and a block surrounding said head, and forming a bearing for said worm.

3. The improved-temporary binder comprising the combination of two plates, filing l members passing through each of said plates,

the filing members of one plate being adapted to telescope with the filing members of the other plate, each of said filing members being provided with an enlarged end adapted to bear against one of the plates, a casing on each plate adapted to inclose the enlarged ends of the filing members, screws disposed in a plurality of the filing members of one of the plates and nuts disposed in the correspondingfiling members of the other plate, said screws being provided with worm-wheel heads, a spindle disposed in one of the casings, worms on the spindle adapted to engage with the wormwheel heads of the screws, blocks in one of the casings adapted to form bearings for the spindle, each of said blocks being provided with a recess for the enlarged ends of the filing members and for the worm-wheel heads, blocks in the other casing adapted to form a bearing for the enlargedcnds of the tiling members, substantially as and for the purpose set "forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

GEORGE HIGGINSON.
